IMPROVEMENT IN CARS FOR ELEVATED RAlLWAYS.

Specification forming part of Letters Patent No. 162,323, dated April20, 1875; application filed March 20, 1875.

To all whom it may concern:

Be it known that I, ROY STONE, of Vandalia, in the county of Gattaraugusand State of New York, have invented anew and Improved Car for ElevatedRailway, of which the following is a specification:

In the accompanying drawing, Figure 1 represents a horizontal section ofmy improved car for elevated railway, on the line 0 0, Fig. 2; Fig. 2, aside elevation, partly in section; Fig. 3, a vertical transverse sectionon the line .90 as, Fig. 2, of the car; and Figs. 4 and 5, respectively,vertical transverse section on line y y, Fig. 5, and side view of one ofthe top bearing-wheels of the car.

Similar letters of reference indicate corresponding parts.

My invention relates to an improved car for that class of elevatedrailways which are constructed on the single-rail plan, or, better, onthreerails (a top bearingand side guiding rails) supported on alongitudinal girder stretched from column to column, the car beingplaced thereon in the nature of a saddle-bag, with symmetrical parts atboth sides of the girder.

The invention consists of a car constructed in saddle-bag fashion atboth sides of the railway, with a double tier of seats arranged oneabove the other, and near the center of car, so that the weight isbrought as much as possible on the top bearing-wheels, which areinclosed in suitable casings of the upper part of the car. The axles ofthe top bearing-wheels turn in journal-boxes. on which the casings restby suitable springs, the axles of the lower side and guard wheels beinghung to the jourrial-boxes, or to separate boxes, with the lower part ofthe car-frame sliding by spring-cushioned bearin gs thereon. The carissurrounded by platforms, and provided with end andcentral staircases, togive ready access to all the seats of the car.

In the drawings illustrating my invention, A represents my improved carfor single-rail or saddle-bags roads, which is constructed insymmetrical parts at both sides of the supporting-girder, and placed ontwo or more separate trucks, B, arranged in the central hollow part ofthe car, and in extensioncasings B for the top bearing-wheels. Thecentral hollow part conforms in size to that of the girder, beingsomewhat larger to allow for the width of the trucks. The caris arrangedon the double-tier plan, the lower tiers with seats facin g toward theoutside, and the upper tiers with seats facing each other, the upperseats being vertically above the lower ones, at such height that thepassengers are not in the least interfered with when rising and sittingdown, and that the weight of all the passengers is brought near thecenter of the car. The upper tiers are protected by an omnibus-shapedextension, 0, with side and end windows and doors, and are reachedconveniently by end staircases 1), connecting the platforms E at bothsides of the car, and by a central door and stairway, D, at the stationside. The end stairways serve to give access to the seats outside of thecasings of the bearing-wheels, while the central seats between thecasings are reached by the middle stairway. The seats of the lower tiersare reached by sliding doors from the platforms, which communicate bythe end stairways, both ends of the car on the stairs being also madeavailable by automaticallyfolding spring-seats, or other suitabledevices, which would be used by smokers and others who prefer to rideoutside. The upper seats are to have the same space as those in anomnibus, and are to be in all respects as comfortable as those in thelower tiers, furnishing, in addition to the outside seats, convenientaccommodation for a large number of passengers. The platforms areprovided with suitable railings, and hinged communicating end doors, bywhich the guards may pass along the whole length of the train. The casing B of the car rests on strong supporting-springsa, placed on thejournal-boxes b of the upper bearingwheels F of the trucks B. The topbearing-wheels F run by double flanges on the top rail of the girder,the axles Got the lower guiding-wheels H being either hung to thejournal-boxes b or to separate boxes d, placed outside of the same onthe shafts of the bearing-wheels, as shown in Figs. 4 and 5. The axles Gare bent in the middle part in outwardly-inclined direction to adjustthemselves to the shape of the girder, and carry at their upper verticalparts the guard-wheels H, and at their vertical lower ends theguiding-wheels H,which are so connected with the bearing-wheels that aconstant position with relation to the bottom. rails is retained,however much the car may rise or fall on its springs, theirguard-flanges coinin g only in exceptional cases in actual contact withthe side rails. The lower part of the car bears by semicircularspring-cushioned bearings or supports 6 above and below theguiding-wheels H on the axles g, so as to allow the car to slide thereonindependently of the motion of the trucks on the rails. The guaml-wheelsH bear on the top rail below the bearing-wheel whenever the car, byoverloading on one side, tends to incline in that direction, so that itis not important to preserve an equilibrium of the car, as theguardwheels, in addition to the guiding-wheels at the bottom, hold thecar level, while the girder, from its form and construction, issufficiently strong to resist the twisting strain which resultstherefrom without causing too great friction thereon. The axles of thebearing-wheels are short, and free to move forward and back at eitherend as far as the car-connecting springs will permit, which allows thebearing-wheels of the trucks to turn, so as to adjust themselves to anycurve of the rail independently of each other and of the body of thecar, thus avoiding all friction of flanges, or danger of climbing therails. The pendent axles of the guiding-wheels are hung to the boxes ofthe bearing-wheels in such a manner as to freely admit the adjustment ofthe latter, while preserving the rigidity of the trucks in lateraldirection and the upright position of the bearing-wheels.

The locomotives are built in the same way as the cars by bringing thecenter of gravity below-the rail, and having guide-wheels in the samemanner. 7

1 For heavy trains or steep grades horizontal driving wheels andvertical guiding wheels may be used, the tractive force being increasedat pleasure, as this form of lateral railways is specially adapted forsuch an arrangement.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In a car for elevated single-rail road, thecombination of a lower tier or tiers of seats, near its center, with asimilar tier or tiers vertically above the lower tier or tiers,substantially as and for the purpose set forth.

2. In a car for elevated single-rail ways, the combination of sideplatforms, communicating end stairways, and a central stairway atstation side, for giving ready access to the upper and lower tiers ofseats, as set forth.

3. A saddle-car having two wheel-casings and cushioned base-supports, incombination with spring-supporting trucks, substantially as and for thepurpose set forth.

4. In the car-supporting truck adapted to shape of girder, thecombination of top wheel, having flexible bearings, with upper guard andlower guiding wheels, substantially as and for the purpose set forth.
